Morse Code - A Security Enhancer

Manisha Barse, Rodney Manuel

Abstract: Morse code was popularly known as the language of dots and dashes. Years later, this language came up with improvised versions like transmitting text information as a series of toggling tones, changing brightness levels, or ticks that can be directly decoded by a skilled listener or a observer without the use of any special type of equipment. It has been the most simplest and inexpensive method of transmitting and receiving messages. Over the years this method was mainly used in radio communication but today this methodology has many applications in aviation, navy and assistive methodology like helping people with disabilities to communicate. This paper demonstrates a basic model of transmitting Morse code through the keyboard via DB9 connector, encoding the alphabets with the help of PIC microcontroller and displaying the transmitted as well the decoded alphabets on the LCD.
